Description

Technical Field

[0001] This utility model relates to the field of plastic pipe processing, and in particular to a plastic pipe threading device. Background Technology

[0002] Plastic pipes are generally made from synthetic resin as the base material, with the addition of stabilizers, lubricants, plasticizers, and other additives, and are manufactured through extrusion molding. They are widely used in building water supply and drainage, sewage, rainwater drainage, and electrical wiring systems. Plastic pipes can be classified into two categories according to their material properties: thermoplastic (such as PVC, PE, PP, etc.) and thermosetting (such as phenolic resin).

[0003] In practical applications, plastic pipe fittings often require threaded connections to meet different installation needs. Therefore, threading the ends of plastic pipe fittings is a common processing procedure.

[0004] Existing tapping equipment, such as the large pipe tapping machine disclosed in Chinese Patent CN207464360U, includes a base, a lifting pipe fitting placement seat, a fixing component, and a slidingly arranged motor tapping component. It can adapt to internal wall tapping operations on pipe fittings of different sizes and does not require frequent fixture changes. However, it is only suitable for internal wall tapping and cannot meet the needs of external wall thread processing for plastic pipe fittings. Manual operation is still required, resulting in low efficiency, high labor intensity, and unstable processing quality. Therefore, a plastic pipe tapping device is proposed to solve the above problems. Utility Model Content

[0005] The main purpose of this utility model is to provide a plastic tube splitting device to solve the problem that the functional units of existing splitting equipment do not have both internal and external splitting functions at the same time.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a plastic tube unwinding device, including a tube body, and further including:

[0007] Support frame one includes a base plate, with vertical rods at the four corners of the top of the base plate, a top plate at the top of the vertical rods, and an insertion hole at the center of the top plate;

[0008] The clamping mechanism is located on the top of the top plate and can clamp the tube body that penetrates the insertion hole;

[0009] A lifting and rotating mechanism, which is mounted on the base plate, includes a processing table that can be lifted and rotated simultaneously;

[0010] A spacing adjustment mechanism is mounted on a processing table and includes two adjustment seats that can move in opposite or disjoint directions;

[0011] There are two thread-cutting parts, which are respectively set on two adjusting seats. Each thread-cutting part includes a support plate, and a thread-cutting head is provided on the top of the support plate. The inner and outer sides of the thread-cutting head are respectively provided with threads for cutting the outer and inner sides of the tube body.

[0012] In the preferred embodiment, the clamping mechanism is a multi-jaw chuck.

[0013] In the preferred embodiment, the clamping mechanism consists of multiple clamping components. Each clamping component includes an extension support seat located on the outer side of the top plate. A telescopic cylinder is located on the top of the extension support seat. The telescopic end of the telescopic cylinder faces the insertion hole and is equipped with an arc-shaped clamping plate.

[0014] In the preferred embodiment, the vertical rod is a cylindrical rod.

[0015] In the preferred embodiment, the lifting and rotating mechanism includes a lifting platform and a lifting telescopic cylinder. The lifting platform is slidably mounted on the vertical rod through lifting holes provided at the four corners. A rotating shaft seat is provided on the top of the lifting platform, and the processing table is rotatably mounted in the rotating shaft seat. A central hole is provided at the center of the lifting platform, and a driven gear ring is provided at the bottom of the processing table located in the central hole. A second support frame is provided on the telescopic end of the lifting telescopic cylinder. The top of the second support frame is fixed to the lifting platform, and a drive device is provided inside it. A transmission gear that meshes with the driven gear ring is provided on the output shaft of the drive device.

[0016] In the preferred embodiment, the second support frame includes multiple support blocks arranged in a ring at equal intervals, and the top of the support blocks is provided with a ring support seat, the top of the ring support seat being connected to the lifting platform.

[0017] In the preferred embodiment, the spacing adjustment mechanism includes a groove on the top of the processing table, in which two sliding limit rods and a rotatable positive and negative threaded screw are fixed. Two adjustment seats are respectively threaded on two opposite threaded sections of the positive and negative threaded screw and slide in cooperation with the two sliding limit rods. One end of the positive and negative threaded screw passes through the groove and is connected to a rotating handle.

[0018] In the preferred embodiment, support feet are provided at all four corners of the bottom of the base plate.

[0019] This invention provides a plastic pipe threading device. By incorporating a support frame, a clamping mechanism, a lifting and rotating mechanism, a spacing adjustment mechanism, and two threading processing sections respectively mounted on adjusting seats, it can selectively perform threading processing on the outer or inner wall of the plastic pipe according to actual needs. Simultaneously, the lifting and rotating mechanism drives the pipe body to rotate, and in conjunction with the adjustable-spacing threading processing sections, it achieves thread processing on plastic pipes of different specifications, demonstrating strong adaptability. This device effectively improves the efficiency of plastic pipe threading, reduces manual labor intensity, and enhances processing quality. Attached Figure Description

Detailed Implementation

[0026] like Figure 1-4 As shown, a plastic tube splitting device includes a tube body 6, a support frame 1, a clamping mechanism 2, a lifting and rotating mechanism 3, a spacing adjustment mechanism 4, and a splitting processing section 5. The support frame 1 includes a base plate 101, and vertical rods 102 are provided at the four corners of the top of the base plate 101. In this embodiment, the vertical rods 102 are cylindrical rods. A top plate 103 is provided at the top of the vertical rods 102, and an insertion hole 104 is provided at the center of the top plate 103 for inserting the tube body 6.

[0027] The clamping mechanism 2 is located on the top of the top plate 103 and can clamp the tube 6 that passes through the insertion hole 104, thereby fixing the tube 6 that needs to be unscrewed.

[0028] In the preferred embodiment, the clamping mechanism 2 is a multi-jaw chuck, which is not shown in the figure. The multi-jaw chuck is a common commercially available pneumatic chuck structure, so it will not be described in detail here.

[0029] In another preferred embodiment, the clamping mechanism 2 consists of multiple clamping components, four in this embodiment, arranged in a cross shape on the top plate 103. Each clamping component specifically includes an extension support 201 disposed on the outside of the top plate 103. The extension support 201 includes an extension plate and a reinforcing rib disposed between the bottom of the extension plate and the bottom of the top plate 103. A telescopic cylinder 202 is disposed on the top of the extension support 201. In this embodiment, the telescopic cylinder 202 is an electric telescopic cylinder. The telescopic end of the telescopic cylinder 202 is directly opposite the insertion hole 104 and is provided with an arc-shaped clamping plate 203. The arc-shaped clamping plate 203 clamps the tube body 6 by the telescopic extension and retraction of the telescopic cylinder 202.

[0030] It should be noted that the four telescopic cylinders 202 are synchronously telescopically controlled through a high-precision servo system, which is existing technology and therefore will not be described in detail here.

[0031] The lifting and rotating mechanism 3 is mounted on the base plate 101 and includes a processing table 306 that can be lifted and rotated simultaneously.

[0032] Furthermore, the lifting and rotating mechanism 3 includes a lifting platform 302 and a lifting telescopic cylinder 301. The lifting telescopic cylinder 301 is a hydraulic telescopic cylinder. The lifting platform 302 is slidably fitted onto the vertical rod 102 through lifting holes 303 provided at its four corners, thereby achieving stable lifting and lowering. A rotating bearing 305 is provided on the top of the lifting platform 302, and the processing table 306 is rotatably mounted in the rotating bearing 305. A central hole 307 is provided at the center of the lifting platform 302, and a processing table 306 is provided at the bottom of the processing table 306 located at the central hole 307. The driven gear ring 308 is fixed to the bottom of the processing table 306 by welding or bolts. The telescopic end of the lifting telescopic cylinder 301 is provided with a support frame 304. The top of the support frame 304 is fixed to the lifting table 302. The drive device 309 is provided inside the support frame 304. The output shaft of the drive device 309 is provided with a transmission gear 310 that meshes with the driven gear ring 308. The support frame 304 provides space for the arrangement of the drive device 309 and provides support.

[0033] With this design, the lifting and telescopic cylinder 301 can be used to lift and lower the lifting platform 302 and its structure. The driving device 309 can drive the processing table 306 to rotate in the rotating shaft seat 305, thereby achieving rotation during the lifting and lowering process, and thus enabling the wire-cutting processing unit 5 to perform wire-cutting work on the tube body 6.

[0034] In a preferred embodiment, the support frame 304 includes a plurality of support blocks arranged in a ring at equal intervals. In this embodiment, there are four support blocks. The top of the support block is provided with a ring support seat, and the top of the ring support seat is connected to the lifting platform 302. With this design, the gap between the support blocks can be used to arrange the connecting lines required by the drive device 309.

[0035] In this embodiment, the drive device 309 is a combination structure of a motor and a reducer.

[0036] The spacing adjustment mechanism 4 is mounted on the processing table 306 and includes two adjustment seats 405 that can move in opposite or disjoint directions.

[0037] In a preferred embodiment, the spacing adjustment mechanism 4 includes a groove 401 disposed on the top of the processing table 306. Two sliding limit rods 402 and a rotatable positive and negative threaded rod 403 are fixed in the groove 401. Bearings for rotatably mounting the positive and negative threaded rod 403 are provided at both ends of the groove 401. Two adjustment seats 405 are respectively threaded on two opposite threaded sections of the positive and negative threaded rod 403 and slide in cooperation with the two sliding limit rods 402. The adjustment seats 405 are provided with corresponding threaded holes and sliding holes. One end of the positive and negative threaded rod 403 passes through the groove 401 and is connected to a rotating handle 404.

[0038] With this design, the rotation of the forward and reverse threaded screws 403 can be controlled by rotating the handle 404, and then the two adjusting seats 405 can be moved in opposite or separate directions under the sliding limit rod 402.

[0039] There are two thread-cutting processing units 5, which are respectively set on two adjusting seats 405. The thread-cutting processing unit 5 includes a support plate 501. The length of the support plate 501 is greater than the length required for thread cutting. A thread-cutting processing head 502 is provided on the top of the support plate 501. The inner and outer sides of the thread-cutting processing head 502 are respectively provided with thread teeth for cutting the outer and inner sides of the tube body 6.

[0040] This design allows the movement of the two adjusting seats 405 to control the distance between the two wire-cutting processing parts 5, thereby adapting to different diameters and the positional requirements for cutting inner and outer wall wires. At the same time, in conjunction with the lifting and rotation of the lifting and rotating mechanism 3, it enables the wire-cutting work on the inner or outer wall of the tube body 6.

[0041] In the preferred embodiment, support feet 105 are provided at the four corners of the bottom of the base plate 101.

[0042] In use, the tube body 6 is vertically inserted into the insertion hole 104 and fixed above the wire-cutting part 5 by the clamping mechanism 2. Then, the spacing adjustment mechanism 4 is used to adjust the two wire-cutting parts 5 to a suitable spacing to match the size of the tube body 6 and the position requirements of inner wall wire cutting or outer wall wire cutting. Then, the lifting and rotating mechanism 3 is used to rotate and raise the two wire-cutting parts 5 to realize the wire cutting of the tube body 6.

[0043] The above embodiments are merely preferred technical solutions of this utility model and should not be considered as limitations on this utility model. The protection scope of this utility model should be the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
